Abstract

in English, Polish

CARS (Coherent Anti-Stokes Raman Scattering) microscopy is an imaging method for living cells visualization as well as for food or cosmetics material analysis without the need for staining. The near infrared laser source generates the CARS signal - the characteristic intrinsic vibrational contrast of the molecules in a sample which is no longer caused by staining, but by the molecules themselves. It provides the benefit of a non-toxic, non-destructive and almost noninvasive method for sample imaging. CARS can easily be combined with fluorescence confocal microscopy so it is an excellent complementary imaging method. In this article we showed some of the applications for this technology: imaging of lipid droplets inside human HaCaT cells and analysis of the composition of cosmetic products. Moreover we believe, that soon new fields of application become accessible for this rapidly developing branch of microscopy.
